Remember when, less than 3 years ago, SF projected a $108M surplus for the next two years?

Woulda been a nice time to clean up some of this technical debt!

Or how about the SF Emergency Sirens, taken offline in late 2019 for a "2 year" upgrade plan that officeholders implied was already in place?

In August 2023, with no progress whatsover, with the Maui fire disaster fresh on their minds, Mayor Breed & Supervisors President Peskin touted they'd finally funded a plan to return them to service soon: https://www.sf.gov/news/mayor-breed-and-board-president-pesk...

In that same August 2023 timeframe, Peskin said the plan would bring this "need to have" system "up and running" & to "state of the art" by end of 2024, for $5.5M: https://www.cbsnews.com/sanfrancisco/news/san-francisco-city...

Of course, this was just more blatant self-exonerating bullshit from our local political machines immune from any real accountability for incompetence in basic public functions.

A mere 6 months later in February 2024, nothing's been started, Peskin admitted "we don't even have a plan", the department is still waiting until "funding is identified", and the cost estimate has ballooned to $20.5m: https://abc7news.com/san-francisco-sirens-emergency-911-aler...

That works out to $170K+ for each of 119 units – units that each could probably just be a weatherized consumer-grade handheld device with multiple mobile/packet/sat radios, & a simple authenticated-playback app, mounted on existing poles that presumably already have power and even loudspeakers.

Sirens don't even need to be that complicated. A motor, a noise generator wheel (basically just a big spinning squirrelcage fan), and a horn. You could toggle them on/off with a simple relay/contactor.
These "sirens" actually need to be able to play spoken announcements - something they did easily since about 2005, before the fumbled 2019-2024 shutdown/upgrade.

More history, through January 2022, via JWZ's blog:

JWZ doesn't like HN and doesn't want his site being linked to on here so your URL redirects to a crude image.
what a delightfully epic troll, good on jwz :)))
Now that you mention it, I do remember hearing the spoken message every Tuesday.

Still, a big loudspeaker is even simpler than a classical motorized siren. No moving parts!

Yep! And as of the shutdown over 4 years ago, even if their control plane was insecure, they presumably had 119 working loudspeakers of the proper loudness/weatherproofing/etc.
